media: Add AV1 uAPI

2023-06-09T15:13:01+00:00

This patch adds the AOMedia Video 1 (AV1) kernel uAPI. This design is based on currently available AV1 API implementations and aims to support the development of AV1 stateless video codecs on Linux.

media: v4l2-ctrls: Fix doc for v4l2_ctrl_request_hdl_find

2023-03-20T15:21:47+00:00

We should call v4l2_ctrl_request_hdl_put() instead of v4l2_ctrl_request_put_hdl(). Fix the typo. Signed-off-by: Miaoqian Lin Reviewed-by: Nicolas Dufresne Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: v4l2-ctrls: drop 'elems' argument from control type ops.

2022-09-24T06:49:06+00:00

The type ops for equal, init and validate have an elems argument, but this can be taken from struct v4l2_ctrl: ctrl->elems for equal and init, and ctrl->new_elems for validate (since you are validating a new control value). So drop this argument and update all callers. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: v4l2-ctrls: Export default v4l2_ctrl_type_ops callbacks

2022-08-29T13:32:13+00:00

Export the callback functions of the default v4l2 control type operations such as a driver defining its own operations could reuse some of them. Signed-off-by: Xavier Roumegue Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: v4l2-ctrls: optimize type_ops for arrays

2022-08-29T13:32:13+00:00

Initializing arrays and validating or checking for equality of arrays is suboptimal since it does this per element. Change the ops to operate on the whole payload to speed up array operations. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: v4l2-ctrls: add v4l2_ctrl_modify_dimensions

2022-08-19T11:47:54+00:00

Add a new function to modify the dimensions of an array control. This is typically used if the array size depends on e.g. the currently selected video format. Signed-off-by: Hans Verkuil Reviewed-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

media: v4l2-ctrls: alloc arrays in ctrl_ref

2022-08-19T11:47:00+00:00

Also allocate space for arrays in struct ctrl_ref. This is in preparation for allowing to change the array size from a driver. Signed-off-by: Hans Verkuil Reviewed-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

media: v4l2-ctrls: allocate space for arrays

2022-08-19T11:46:11+00:00

Just like dynamic arrays, also allocate space for regular arrays. This is in preparation for allowing to change the array size from a driver. Signed-off-by: Hans Verkuil Reviewed-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

media: uapi: move HEVC stateless controls out of staging

2022-07-15T16:36:58+00:00

HEVC uAPI is used by 2 mainline drivers (Hantro, Cedrus) and at least 2 out-of-tree drivers (rkvdec, RPi). The uAPI has been reviewed so it is time to make it 'public' by un-staging it.

media: v4l2-ctrls: add support for dynamically allocated arrays.

2022-07-15T15:20:53+00:00

Implement support for dynamically allocated arrays. Most of the changes concern keeping track of the number of elements of the array and the number of elements allocated for the array and reallocating memory if needed.
